The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in Ruili City, Yunnan Province, are as follows: food waste 56.55%, paper 14.25%, rubber 14.98%, textiles (fibers) 3.76%, wood and bamboo 8.44%, ash and soil 0%, bricks, tiles and ceramics 0%, glass 1.53%, metal 0.48%, and others 0%. The moisture content is 56.67%, higher calorific value of 7240.08 kJ/kg, and lower calorific value of 5245. 3 kJ/kg. Waste treatment activities are based on an average urban/municipal waste mixture and are not suitable for specific waste types such as plastics, paper, cardboard, etc. If your waste consists of a specific waste mixture, please inventory the corresponding waste separately. For each kg of this waste, 0.205 kg of slag and 0. Fly ash and炉渣are landfilled after precious metal recovery; fly ash is solidified with cement at a ratio of 1:1. The average heat efficiency of waste heat power generation is 22%; in the process of waste heat supply, there is no conversion between different forms of heat and energy, so the heat efficiency is higher, with an average value of 64%. Through a comprehensive look at the thermal efficiency of waste heat power generation and direct heat supply processes, 15% of the heat generated from the incineration process is used for power generation and 56% is used for direct heating.
